Description

Abstract: The compact AMS devices are the tendency of AMS development. Based on the previously developed air-insulated AMS, the compact AMS device with a terminal voltage of 0.25 MV has been established. In this paper, a low detection limit measurement method for 239Pu using compact accelerator mass spectrometry (AMS) has been presented. A measurement technique for 239Pu was established based on the systematic study of ion extraction, transmission, and ion detection using this device. The measurement performance is tested using standard samples and blank samples. The detection limit of 239Pu is about 0.1fg, and the measurement uncertainty of standard samples meet within 5%. This device is currently available for routine measurement of 239Pu samples.
